Zambo launch: lead generation for local services\n\nHi [Name],\n\nI’m reaching out because Zambo is live. We built this specifically for contractors and local service businesses who need qualified leads without the agency markup or the slow turnaround.\n\nHere is the reality of the current MVP:\n\nZambo Stack lets you input a trade and a city to get five qualified leads with contact info in under 60 seconds. It supports 24 trades across any US city. There is no auth, no API key, and no signup required. You get three free searches per day per IP.\n\nTo be transparent about our current status: we are in early launch. We do not have a list of completed case studies or verified customer testimonials yet. In our initial testing, we queried the Austin, TX market for web design services and received zero results. This highlights that lead availability depends on real-time data density in specific verticals. A receipt from our system confirms that the saved bytes remain unchanged, but it does not guarantee that the data is correct or that leads exist for every query.\n\nWe are not inventing success metrics. We are sharing a functional tool that works when the data is there, and we are transparent when it isn’t.\n\nIf you are a contractor or a local service provider, I want you to test it right now. The value is in the speed: 60 seconds to see if there is demand in your specific zip code.\n\nTry the tool here: [Insert Link to Zambo]\n\nPick your trade. Pick your city. Run the search.\n\nIf you get a result, you have a lead. If you don’t, you have a data point. Either way, you learn more in a minute than most salespeople learn in a week.\n\nWe are building this in public. If you try it and find a bug, or if you find a lead that doesn’t convert, tell me. I read every message.\n\nNo pitch deck. No sales call. Just the tool.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ddb3f291d73fcc603867b1b8e46e68d7679e69e4aaa44a11414e640fe51fafe5","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:4fa513dc98be8f121c2da0a78f130695cd0b887f6e9092c7c9702df0059204d4","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:f68d8b729aec0d817a6094df3110bb3bb116c14ee02787ac584131afd6b35f0d","anchor":{"event_id":"f6caea3325e2d7b619b06b0b1244f3e581ec9afea5e1447fce0665f32d94e77b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-03T22:40:36.125Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-03T22:40:35.573Z","evidence_url":null,"receipt_uuid":"a4f97020-d4f0-43c0-87ad-f2ce777b662d","output_sha256":"sha256:8f4c8f74bbbbdec5f289d542c3420a6463b7e1b5734f291baeb3a25127c51e29","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-03T22:40:35.573Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8f4c8f74bbbbdec5f289d542c3420a6463b7e1b5734f291baeb3a25127c51e29\",\"receipt_uuid\":\"a4f97020-d4f0-43c0-87ad-f2ce777b662d\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-11-03T22:40:35.573Z","detail":"The receipt store reports 2026-11-03T22:40:35.573Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
